Okay, I have changed my mind so many times about what I am gonna get for my new 33 gallon, but now I will finally put down my foot. I am going to get a pair of firemouth cichlids (1 male, 1 female). I still dont know what I am going to get for a bottom feeder, could someone tell me what I could get for this setup? I am going to have a couple of clay pots in there for hidey spaces, and of course that awesome cave I made. If anyone has suggestions on what I could do for care with this setup, please tell me. Thanks! 
Edit: also, could someone tell me about the firemouth breeding method? Is it easy to do, and how do you take care of the fry?
